10. Substances influence some people
If you are talking to a guy who has been drinking all night long, he might seem a bit more friendly than usual. Be aware of this and take all that he says with a grain of salt. Most people's personalities change when they consume alcohol. A normally shy person can easily come across as a very forward person. Guys may become more chatty with you and show a lot of interest, when, in fact, it is just the alcohol. And most people when drunk are usually just interested in sex. You might want to meet with the guy after the influences have worn off and see if his "feelings" go any deeper.
